What's in the garden?

 At Risk  

Best Practice  

  • Metal or plastic single skin tanks

  • Many tanks over 10 years old

  • Poorly supported base

  • Poorly located

  • Not fitted to regulations

  • Signs of bleaching or cracking

  • Signs of rust

Building and environmental regulations

If the tank is near to a drain, bore hole,
river or other water watercourse, and a
pollution incident would occur if the tank
leaked or was overfilled, the chances are
that a bunded tank is needed by law.

  • Integrally bunded (tank within a tank)

  • Top offtake oil supply

  • Contents gauge

  • Overfill prevention device

  • Fitted to building regulations (BS5410 Part J)

  • CE marked

  • Regularly serviced 


Oil tanks should be sited in accordance
with building regulations, which protects
then from a fire that may be started near by.
Siting is typically 1.8m from openings into
building and 760mm from a combustible
boundary. If this can’t be achieved, a fire
barrier can be erected between the tank and hazard.
